Hi,

Filtering doen't seem to work for a TimeSpan column in instant feed back mode through either filter dropdown or automatic filter row or filter editor.
Thanks.

    Hi.
    I added a sample project showing this issue.
    Please activate the wcf data service first by viewing it in browser to load the nuget packages before running the project.

      Hi Güray,
      Many thanks for your sample. I have reproduced this exception and will discuss it with our developers. I will update this ticket once I have any news. Thank you for your patience in advance.

        Thank you for your patience. It appears that there is an issue with generating queries when data is filtered by a TimeSpan field. Our developers will additionally research this issue. We will let you know once we find a solution.

        We have fixed the issue described in this ticket and will include the fix in our next maintenance update. To apply this solution before the official update, request a hotfix by clicking the corresponding link for product versions you require.

        Note: Hotfixes may be unavailable for beta versions and updates that are about to be released.

        Additional information:

        We fixed the issue with the filter dropdown and FilterEditor. However, there is no way to fix the issue with AutoFilterRow since this issue occurs due to an OData restriction. Our AutoFilterRow generates queries using the "StartWith" operator. OData supports this operator only with the string type and doesn't support operations like ToString(). Thus, there is no way to fix this issue on our side since OData won't be able to compare the TimeSpan values that come from AutoFilterRow.
